Application let December 12, 1930. Seal No. 501,870.

This invention relates to that class of de vices known as window channels or guldes such as are commonly employed in automobile bodies to hold slidingly the usual wmdow glass.

A window guide which will satisfactorily meet all the demands of the maker user necessarily must hold the glass rlgldly against vibration and yet prevent bmdmg between the glass and the guide. It must n ot be affected adversely by time, dirt, chmatlc or Weather conditions. It must admit 0f ready assembly; be relatively inexpensiveto manufacture, and when'once installed give maximum service. O

In an endeavor to meet these exactm demands various materials including ru ber, felt, fabric and metal heretofore have been proposed but none of them has been entlrely satisfactory. c

This invention has for its primary object to rovide an improved window channel, which will be devoid of all the inherent defects of prior constructions, and will meet all the demands of the trade. More specifically stated, it provides a window channel which will not dry out and thereby present to the glass a hard unyielding surface as does rubber; which will not absorb and retain water and thereby swell and cause binding on the glass, as do felt and fabric; which does not permit rattle or cause binding as does metal, dependent whether it is loose or snug on the glass; but which will, under all conditions, provide the proper cushioning effect for the glass and the requisite amount of friction thereon. l

This object of constructing an improved window glass channel has been attained by providing a relatively heavy fibrous base and by securing to said base, due to their being vulcanized in a waterproof sheet of rubber, cemented or otherwise attached to the base, a myriad of relatively stiff hairs, preferably goats hair, which project perpendicular to the face of the rubber sheet, thereafter folding a strip of said composite sheet into a substantially U-shape channel and securing it within the usual rabbet commonly provided for the purpose. With the strip so folded there is provided a central longitudinal groove of which the sides and bottom I are formed by hairs standing on end and adapted frictionally to engage the glass nserted therein, and there is preferably sufficient frictional engagement between the ends of the hairs and glass member to support said member in its various positions, except under strains incident to the moving vehicle, which insures that there will be Suffcient frictional engagement to prevent undesirable rattling.

If desired, strips of suitable material, such for example as metal or Celluloid, may be secured to the fibrous base at the vside opposite to that to which the hairs project thereby to stifen the glass channel.

Other objects and advantages will be in part indicated in the following description and1 in part rendered apparent therefrom in connection with the annexed dra To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed as a part of this disclosure and, in such drawings, like characters of reference denote corresponding parts throughout all the views, of which Figure 1 is a perspective view of the strip of material from which the improved Window channel may be made. Fig. 2 is a sectional view showing the improved window channel located Within the usual rabbet formed in the window frame and held in place by the usual garnish moulding. Fig. 3 is a view similar to Fig. 1 but showing the strip grooved for a purpose hereinafter to be explained. Fig. 4 is a disassembled perspective view of the strip shown in Fig. 3 folded into U-shape, together with the stifening strips adapted to be secured thereto. Fig. 5 is a view similar to Fig. 2 but showing the channel formed of the elements illustrated in Fig. 4.

ISG

Figs. 8 and 9 are detail sectional views illustrating the bending action of the hairs as the glass is moved in opposite directions.

Referring more specifically to the drawings and particularly to Figs. 1, 2, 8 and 9, the improved window channel is disclosed as comprising a base 1 of fabric or other suitable iiexible material to which is secured, by any suitable means such for example as by cement 2, a sheet 3 of rubber or other water; proof material. Embedded into or otherwise secured to the sheet 3 are a myriad of relatively sti hairs 4 which project outwardly perpendicular to the face of the rubber sheet. When the strip is folded into U-shape form, as shown in Fig. 2, the hairs form a cushion for the glass 5 slidable in the central longitudinal groove therebetween. Goats hair has been found admirably well suited for this purpose as it is sutciently stiff to stand up satisfactorily under the adverse conditions to which such devices are subjected and to afford the necessary friction, yet suiiciently flexible to bend as the direction of movement of the glass is changed thereby preventing undue binding on the glass. The use of other relatively stiff hair is, however, contemplated.

As shown in Fig. 2 this improved channel may be inserted directly in the rabbet 6 formed in the frame 7 and held therein by a garnish molding 8, suitably secured to the frame. To hold the channel in place in the rabbet the frame is formed with a lip?a and the garnish moulding with a lip 8a which engage the edges of the channel strip.

Tf desired the sheet of waterproof material may be made heavier and the fabric base 1 dispensed with. Also the hairs may be arranged to engage the sides only of the glass, other means being provided to prevent edg wise movement of the glass.

Among the advantages attained by the present window channel is that the entire groove for the glass is provided with a waterproof lining which dprevents deterioration commonly experience with other forms of guides due to their repeatedly being subjected to water. Furthermore, due to the fact that the hairs are relatively stiff and thereby stand somewhat spaced apart they permit free passage of water therebetween, therefore the channel does not retain water as docs felt or fabric but instead is quick drying. Still further neither the rubber lining nor the hairs swell when subjected to water nor do the hairs vreadily lose their resiliency. Therefore the friction between the glass and the guide channel is substantially constant under all conditions of use.

Still another advantage is that it may more readily be inserted in the usual frame and assembled with the glass therein than any prior constructions. Referring to Fig. 2 it will be perceived that with the garnish terraces moulding removed from both sides of the window strips similar to those shown in either Figs. 1 orv 3 may be folded into L-shape form and inserted into the rabbets 6, provided by the opposite sides of the frame 7, with one edge thereof in engagement with the lips 7"l and the main body of the strips extending along the faces 7b of the frame as shown in dotted lines, Fig. 2. Then the glass may be inserted by a horizontal movement in a direction perpendicular to the face of the glass, next the other side of the strip may be folded against the glass, thus completing the U-shape and the garnish moulding may be attached to the frame to hold the parts in their assembled position.

As shown in Fig. 9 the hairs 4 are of such length that the channel therebetween is of slightly less width than the glass adapted to slidev therein. to exert a slight pressure on the glass thereby producing the requisite friction thereon. During movement of the glass the hairs will bend in the direction of such movement, as illustrated in Figs. 8 and 9.

Tf desired the mat of hair on the strip may be groove-d longitudinally as shown at 9. This may be effected in any suitable way such, for example, as by removing the hairs from a portion of the strip. These grooves form a clearance and permit ready bending of the strip into U-shape form, as shown in Fig. 4, without compacting the hairs at the corners.

For certain purposes it may be desired to reinforce the channel. This may be effected,

as shown in Figs. 4 and 5 by securing to the side and back walls of the channel metal strips 10 and 11. The side strips 10 preferably are formed with hooked extremities 10u adapted to encase the forward edge 1EL of the flexible base thereby protecting said edge against wear and weather. The strips 10 and 11 may be secured to walls of the channel by having a series of tongues 12 punched therefrom and inserted through the base fabric 1 forming stitches about which the parts are folded as shown in Fig. 5.

Figs. 6 and 7 illustrate another form of stiifening means for the channel. This consists of strips 13 of Celluloid or other suitable material adhesively secured to the back of the base strip 1, the strips 13 being separated along the lines at which the base strip is adapted to be folded. In this form also the reinforcing strips are adapted to cover the marginal edges of the base strip as shown at 13a.
